Project Curve / Intersect outside of sketch

I'm new to the forum and NX10, but have extensive experience with 6 and 8.I couldn't find an answer to my problem... :/

I'm baffled that some things (here I'm asking mostly about derived curves - projected or intersected, but I also mean splines for example) are not inside the sketch ferature. Instead they are just features on the history tree. Even though I created them while doing a sketch.

Furthermore I cannot use them in the sketch (extend, trim, make corner, etc.).

Can I change this or do all such features behave as 3D sketch features...?

Re: Project Curve / Intersect outside of sketch

well, these features are not part of the sketch, and by nature they are not limited to a 2D Plane. However, a sktech is.

When you work in a sketch in direct sketch mode, you can also access commands outside the sketcher, I guess this is the reason why you ended up with this features.

What you can do, is that you can project these curves into the sketch. Then you can use the command "trim recipe curves" to trim them to other sketch geometry (only trim, not extend!). Of course, the 3D curve features must be created before the sketch (Timestamp).

Re: Project Curve / Intersect outside of sketch

It is possible to create splines in the sketch; there is also the intersection curve which creates curves in the sketch by intersecting the sketch plane with a solid or face. I suggest using the "sketch in task environment" rather than the "direct sketch" option as it makes it more clear which commands will create a "sketch" curve vs. an external curve.

The direct sketch capability was introduced (I remember it was NX 6) to simplify sketch based design creation workflows, where sketches are rather simple. The focus in this case stays on the whole workflow.

It also enables the user to see immediate impact on model changes when sketch curves are modified (Disable Delay Model Updates during sketch edit). Many clicks can be avoided.

Re: Project Curve / Intersect outside of sketch

You will find more things just as baffling the more you use it. I feel it is typically wise to learn how to customize the interface and utilize Roles effectively - that will pay off when you migrate to a newer version or at least until the Ribbon interface changes to the next "big thing".
